Green endoscopy: British Society of Gastroenterology (BSG), Joint Accreditation Group (JAG) and Centre for Sustainable Health (CSH) joint consensus on practical measures for environmental sustainability in endoscopy.

GI endoscopy is highly resource-intensive with a significant contribution to greenhouse gas (GHG) emissions and waste generation. Sustainable endoscopy in the context of climate change is now the focus of mainstream discussions between endoscopy providers, units and professional societies. In addition to broader global challenges, there are some specific measures relevant to endoscopy units and their practices, which could significantly reduce environmental impact. Awareness of these issues and guidance on practical interventions to mitigate the carbon footprint of GI endoscopy are lacking. In this consensus, we discuss practical measures to reduce the impact of endoscopy on the environment applicable to endoscopy units and practitioners. Adoption of these measures will facilitate and promote new practices and the evolution of a more sustainable specialty.

UK guideline on transition of adolescent and young persons with chronic digestive diseases from paediatric to adult care.

The risks of poor transition include delayed and inappropriate transfer that can result in disengagement with healthcare. Structured transition care can improve control of chronic digestive diseases and long-term health-related outcomes. These are the first nationally developed guidelines on the transition of adolescent and young persons (AYP) with chronic digestive diseases from paediatric to adult care. They were commissioned by the Clinical Services and Standards Committee of the British Society of Gastroenterology under the auspices of the Adolescent and Young Persons (A&YP) Section. Electronic searches for English-language articles were performed with keywords relating to digestive system diseases and transition to adult care in the Medline (via Ovid), PsycInfo (via Ovid), Web of Science and CINAHL databases for studies published from 1980 to September 2014. The quality of evidence and grading of recommendations was appraised using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. The limited number of studies in gastroenterology and hepatology required the addition of relevant studies from other chronic diseases to be included.These guidelines deal specifically with the transition of AYP living with a diagnosis of chronic digestive disease and/or liver disease from paediatric to adult healthcare under the following headings;1. Patient populations involved in AYP transition2. Risks of failing transition or poor transition3. Models of AYP transition4. Patient and carer/parent perspective in AYP transition5. Surgical perspective.

British Society of Gastroenterology Best Practice Guidance: outpatient management of cirrhosis - part 3: special circumstances.

The prevalence of cirrhosis has risen significantly over recent decades and is predicted to rise further. Widespread use of non-invasive testing means cirrhosis is increasingly diagnosed at an earlier stage. Despite this, there are significant variations in outcomes in patients with cirrhosis across the UK, and patients in areas with higher levels of deprivation are more likely to die from their liver disease. This three-part best practice guidance aims to address outpatient management of cirrhosis, in order to standardise care and to reduce the risk of progression, decompensation and mortality from liver disease. Part 1 addresses outpatient management of compensated cirrhosis: screening for hepatocellular cancer, varices and osteoporosis, vaccination and lifestyle measures. Part 2 concentrates on outpatient management of decompensated disease including management of ascites, encephalopathy, varices, nutrition as well as liver transplantation and palliative care. In this, the third part of the guidance, we focus on special circumstances encountered in managing people with cirrhosis, namely surgery, pregnancy, travel, managing bleeding risk for invasive procedures and portal vein thrombosis.

British Society of Gastroenterology Best Practice Guidance: outpatient management of cirrhosis - part 1: compensated cirrhosis.

The prevalence of cirrhosis has risen significantly over recent decades and is predicted to rise further. Widespread use of non-invasive testing means cirrhosis is increasingly diagnosed at an earlier stage. Despite this, there are significant variations in outcomes in patients with cirrhosis across the UK, and patients in areas with higher levels of deprivation are more likely to die from their liver disease. This three-part best practice guidance aims to address outpatient management of cirrhosis, in order to standardise care and to reduce the risk of progression, decompensation and mortality from liver disease. Here, in part one, we focus on outpatient management of compensated cirrhosis, encompassing hepatocellular cancer surveillance, screening for varices and osteoporosis, vaccination and lifestyle measures. We also introduce a compensated cirrhosis care bundle for use in the outpatient setting. Part two concentrates on outpatient management of decompensated disease including management of ascites, encephalopathy, varices, nutrition as well as liver transplantation and palliative care. The third part of the guidance covers special circumstances encountered in managing people with cirrhosis: surgery, pregnancy, travel, managing bleeding risk for invasive procedures and portal vein thrombosis.

British Society of Gastroenterology Best Practice Guidance: outpatient management of cirrhosis - part 2: decompensated cirrhosis.

There are two distinct phases in the natural history of cirrhosis: compensated disease (corresponding to Child Pugh A and early Child Pugh B disease), where the patient may be largely asymptomatic, progressing with increasing portal hypertension and liver dysfunction to decompensated disease (corresponding to Child Pugh late B-C), characterised by the development of overt clinical signs, including jaundice, hepatic encephalopathy (HE), ascites, renal dysfunction and variceal bleeding. The transition from compensated cirrhosis to decompensated cirrhosis (DC) heralds a watershed in the nature and prognosis of the disease. DC is a systemic disease, characterised by multiorgan/system dysfunction, including haemodynamic and immune dysfunction. In this second part of our three-part series on the outpatient management of cirrhosis, we address outpatient management of DC, including management of varices, ascites, HE, nutrition, liver transplantation and palliative care. We also introduce an outpatient DC care bundle. For recommendations on screening for osteoporosis, hepatocellular carcinoma surveillance and vaccination see part one of the guidance. Part 3 of the guidance focusses on special circumstances encountered in patients with cirrhosis, including surgery, pregnancy, travel, management of bleeding risk for invasive procedures and portal vein thrombosis.

Identification of mutations in SLC40A1 that affect ferroportin function and phenotype of human ferroportin iron overload.

BACKGROUND & AIMS: Patients with ferroportin iron overload due to loss-of-function mutations in SLC40A1 have macrophage iron overload, hyperferritinemia, and normal transferrin saturation. In contrast, hepatocellular iron storage, hyperferritinemia, and increased saturation of transferrin are a distinct clinical presentation of ferroportin iron overload that results from SLC40A1 mutations that confer resistance of ferroportin to hepcidin-mediated inactivation. METHODS: SLC40A1 was sequenced in patients from 2 independent pedigrees affected by hepatic iron overload unrelated to HFE. Functions of the ferroportin variants were tested in vitro. RESULTS: A patient heterozygous for the variant p.W158C in SLC40A1 presented with macrophage iron overload, hyperferritinemia, and normal transferrin saturation. A patient with hepatocellular iron storage, hyperferritinemia, and increased transferrin saturation was heterozygous for p.H507R. Expression of the p.W158C form of ferroportin in 293T cells resulted in defective trafficking to the plasma membrane and reduced iron export activity; the iron export activity of cells that expressed the p.H507R form of ferroportin did not differ from cells that expressed ferroportin without this mutation. The p.H507R of ferroportin localizes normally to the plasma membrane but is resistant to hepcidin-mediated inactivation. Addition of a synthetic peptide derived from ferroportin without these mutations (amino acids 500-518) decreased the inhibitory activity of hepcidin in cells, whereas a peptide from the same region, with p.H507R, had no effect on hepcidin activity. CONCLUSIONS: The variant p.W158C in SLC40A1 impairs intracellular trafficking of ferroportin, resulting in reduced iron export. The variant p.H507R does not bind hepcidin in vitro and results in apparent hepcidin resistance.

Delay in Transit: selected recommendations from the NCEPOD report on acute bowel obstruction.

Delayed in Transit, the report of the National Confidential Enquiry into Patient Outcome and Death (NCEPOD) on acute bowel obstruction (ABO), highlighted a number of areas for improvement in this group of patients. The overarching finding was that there were delays in the pathway of care for patients with ABO at every stage of the clinical pathway, including diagnosis, decision-making and the availability of operating theatres. Furthermore, basic measures including hydration, nutritional screening and nutritional assessment were noted to be deficient. Patients who were admitted to non-surgical wards had an increased risk of delayed treatment and subsequently a longer starvation period. There was room for improvement of nutritional screening and assessment on admission, throughout the hospital stay and on discharge. A selection of the report recommendations that address these areas requiring improvement is discussed here.

Stress and its causes in UK gastroenterologists: results of a national survey by the British Society of Gastroenterology.

AIM: Evaluation of stress and its causes in UK gastroenterologists. DESIGN: Questionnaire emailed to all 1932 medical members of the British Society of Gastroenterology. RESULTS: Of 567 respondents (29%), 107 (20%) graded their stress level as 4 or 5 out of 5. Stress levels correlated inversely with self-reported happiness levels (r=-0.60; p<0.001) and with hours slept per night (r=-0.23; p<0.01) and correlated directly with % time off-duty thinking about work (r=0.46; p<0001) and with proportion of nights with broken sleep (r=0.30; p<0.01). Due to stress over the past year, 21% of respondents reported one of the following: consulting their general practitioner (7%), attending occupational health (5%), taking planned time off (7%), taking anxiolytics/antidepressants (6%) and considering suicide (5.5%). These respondents had higher stress and lower happiness levels than the remainder. Stress levels were higher in women and in those working full time but had no other demographic associations.The main causes of stress were excessive clinical work (ranked highest by 47% and most commonly patient-related administration), working conditions beyond control (ranked highest by 15% and most commonly inadequate information technology systems, workspace and secretarial staff) and conflict (ranked highest by 9%). Of eight potential factors, happiness with work showed the closest associations with overall happiness (positive) and overall stress (negative) levels. Talking to someone at work about stress was ranked difficult or impossible by 35%. The highest ranked suggested solutions were relief from some duties and mentoring. CONCLUSIONS: Stress is common and has objective correlates in UK gastroenterologists. The main cause is excessive workload.

A rare clinical presentation of a malignant fibrous histiocytoma within the iliopsoas muscle.

Primary malignant tumours of the iliopsoas compartment are rare clinical entities that are infrequently reported in the literature. Although presenting symptoms vary, this is a very uncommon report of referred pain to the groin and testicular region in a psoas muscle tumour.

Cholangiocarcinoma presenting as hemobilia and recurrent iron-deficiency anemia: a case report.

INTRODUCTION: Iron-deficiency anemia is a relatively common presenting feature of several gastrointestinal malignancies. However, cholangiocarcinoma has rarely been reported as an underlying cause. The association of cholangiocarcinoma with the rare clinical finding of hemobilia is also highly unusual. To our knowledge, this is the first case report of cholangiocarcinoma presenting with acute hemobilia and chronic iron-deficiency anemia. CASE PRESENTATION: We report the case of a Caucasian, 84-year-old woman presenting with recurrent, severe iron-deficiency anemia who was eventually diagnosed with intra-hepatic cholangiocarcinoma, following an acute episode of hemobilia. A right hepatectomy was subsequently performed with curative intent, and our patient has now fully recovered. CONCLUSION: This is a rare example of hemobilia and chronic iron-deficiency anemia in association with cholangiocarcinoma. We suggest that a diagnosis of cholangiocarcinoma should be considered in patients who present with iron-deficiency anemia of unknown cause, particularly in the presence of abnormal liver function.
